Whether it's confirming the roster of "X-Men: Days of Future Past" or revealing new looks for returning "X-Men: First Class" characters, director Bryan Singer's Twitter account always has some new surprise in store for his followers. Continuing his trend of slow reveals via the social media service, Singer released a photo of a uniform with a logo for Trask Industries.

Trask Industries is a reference to a number of characters in Marvel's X-Men universe, all of whom belong to the same family. Bolivar Trask was the creator of the mutant-hunting Sentinels, robots that play a large part in the original "Days of Future Past" comic. Larry Trask, Bolivar's son, was a precognitive mutant that eventually died while fighting a group of Sentinels. Bolivar's daughter, Tanya Trask, was a time traveling member of the Askani with a connection to Rachel Summers and Cable.

The Trask referred to is likely Bolivar, a theory made even more likely by the rumors that actor Peter Dinklage would be portraying the character.
